Thumbnail concepts you can hand straight to your editor
This tool doesn't just suggest "use a shocked face". It returns a complete concept: main subject and pose, background scene, overlay text, colour direction, emotion and where each element sits in the frame.
Concepts are written for gaming click-through: high contrast, one readable idea, and a face or subject that still reads at the small size YouTube actually shows on mobile.
What you get
- Subject, background, text, colour and composition in one brief
- Clean, dramatic, meme, cinematic, minimal and loud styles
- Text kept to three or four words so it reads at thumbnail size
Frequently asked questions
What makes a good gaming thumbnail?
One clear subject, strong contrast against the background, at most four words of text, and an emotion that matches the title's promise.
What size should a YouTube thumbnail be?
1280x720 pixels, 16:9, under 2MB — but design it so it still reads at about 210 pixels wide.
